  • Patent number: 10271119
    Abstract: The present invention prevents a three-dimensional fabric arranged in front surfaces of speakers from flapping due to sound. In the respective front surface sides of, sound-emitting direction regulating members that include annular portions that project forward by a predetermined distance are arranged. A three-dimensional fabric is tensioned and arranged so as to cover the front surface sides of the sound-emitting direction regulating members. When the three-dimensional fabric is pressed against the annular portions configuring the sound-emitting direction regulating members, the annular portions bite into the three-dimensional fabric since the three-dimensional fabric has a predetermined thickness. The annular portions are provided so as to surround diaphragms of the speakers. Sound output from the speakers passes inside the annular portions.

  • Patent number: 10227229
    Abstract: A headrest in which a pad layer is integrally formed, including a portion with a narrow gap, between a mechanism having various types of incorporated functions and a skin member. A shock absorbing member that is an injection-passage-forming member having a foaming raw material injection passage formed so as to run substantially along a direction that is the vertical direction of the headrest in orientation of when a seat is attached, is set in the inside of a skin member, and a foaming raw material for forming the pad layer is injected through the foaming raw material injection passage. The configuration preferably causes the foaming raw material to spread by the foaming start time, as the foaming raw material spreads to the outer side of the headrest, that is, to the inner surface of the skin member, where the pad layer is required to be formed.

  • Patent number: 5614752
    Abstract: A semiconductor device that includes at least one MOS transistor that is formed on a semiconductor substrate, in which there is a structure for protecting circuit elements such as transistors from excessive static electricity from the outside, such as surge input and static electricity generated during the production process. Transistors and diodes are formed so that contact is made between a high impurity concentration diffusion region that forms the source or drain and a low impurity concentration diffusion region that has a conductivity opposite that of the high impurity concentration diffusion region that forms an LDD structure transistor offset. By making contact between a high impurity concentration diffusion region and a low impurity concentration diffusion region, there is formed a circuit element that reduces the junction breakdown voltage. In addition, by using the offset of the CMOS structure, there is no increase in the number of production process steps.

  • Patent number: 5475248
    Abstract: A semiconductor device comprised of a transistor (TR) having a gate electrode, a source region and a drain region, and a ferroelectric capacitor formed above a local oxide film. The capacitor has a ferroelectric film, and upper and lower electrodes that sandwich the film therebetween. The lower electrode and the source region are connected to each other through a wiring or interconnection which is formed of a conductive reaction-preventing film with an Al wiring electrode stacked thereon. The conductive reaction-preventing film is formed of TiN, MoSi, W, etc. If an annealing treatment is carried out for the purpose of improving the characteristics of the semiconductor device or a final protection film is formed after the formation of the wiring electrode, the wiring electrode and the upper electrode do not react with each other. Thus, excellent characteristics of the ferroelectric film are obtained so that a highly integrated ferroelectric memory having high performance can be formed.

  • Patent number: 5293510
    Abstract: The structural body of a ferroelectric capacitor C is located over a source region (23) between a gate electrode (22) and a local oxide film (26). The structural body has a ferroelectric film (29) and an upper electrode (30) and a lower electrode (31) for sandwiching the ferroelectric film (29), and is provided with a conductive oxide film (32) between the lower electrode (31) and the source region (23). The conductive oxide film (32) is ITO, ReO.sub.2, RuO.sub.2 or MoO.sub.3. If an oxygen anneal is conducted after forming the ferroelectric film (29) for the purpose of reforming crystallizability of the ferroelectric film (29), oxygen enters into the conductive oxide film (32) to some extent. As a result, the conductive oxide film (32) is further oxidized, and becomes a so-called oxide barrier or dummy layer.
